２５ Cosmology based on theory of elementary particles【What is the Universe？】Dialogue with the Universe
・The Big Bang model is explained by Cosmology based on theory of elementary particles.
・Elementary particle are explained by several kinds of symmetry in theory of elementary particles.
・Although it is assumed that there are an equivalent amount of substances and anti-matter in the universe from this, it is rare that anti-matter is observed.
・The asymmetry (that is, there is almost no anti-matter) of existence of the substance in the universe is one mystery in theory of elementary particles.
Since the fundamental power of anti-matter is repulsive force, it is thought that anti-matter was diffused at high speed rather than the substance after separation of gravity and antigravity (１０Ｅ−４４（ten to the minus 44th） second after the Big Bang).
